研究了ErxY2-xSiO5和ErxYbyY2-x-ySiO5晶体薄膜在硅光子学高增益介质中的应用。除了溶胶-凝胶法，定向自组装的方法，使用逐层沉积技术，也被引入，以提高结晶度。讨论了Er离子的弛豫过程，阐明了能量传递和合作上转换的贡献。在优化Er含量后，制作了Si光子晶体缝隙ErxY2-xSiO5波导放大器，获得了30 dB/cm的模式增益。这一成就表明了硅芯片上紧凑和高光学增益器件的潜力。(C)2014中国激光出版社
ErxY2-xSiO5 and ErxYbyY2-x-ySiO5 crystalline thin films were investigated to apply to the high-gain media for silicon photonics. In addition to the sol-gel method, the directed self-assembly approach, using layer-by-layer deposition techniques, was also introduced to improve the crystallinity. The relaxation processes in Er ions were discussed to clarify the contribution of the energy transfer and cooperative upconversion. After optimization of the Er content, a Si photonic crystal slot ErxY2-xSiO5 waveguide amplifier was fabricated, and a 30 dB/cm modal gain was demonstrated. This achievement demonstrates the potential for compact and high optical gain devices on Si chips. (C) 2014 Chinese Laser Press
